[jira] [Updated] (JDO-721) Specifying NULL elements positioning in ordered columns
[ https://issues.apache.org/jira/browse/JDO-721?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Craig L Russell updated JDO-721: Fix Version/s: JDO 3 maintenance release 2 (3.2) Specifying NULL elements positioning in ordered columns --- Key: JDO-721 URL: https://issues.apache.org/jira/browse/JDO-721 Project: JDO Issue Type: Improvement Components: specification Affects Versions: JDO 3 update 1 (3.0.1) Reporter: Muhammad Gelbana Priority: Minor Labels: jdoql Fix For: JDO 3 maintenance release 2 (3.2) I don't know about other RDBMS but in MySQL ordering, it's possible to specify whether NULL column fields are placed in the beginning or at the end of the ordering, i.e.: ORDER BY `values_column` IS NULL DESC [values_column] NULL NULL value1 value2 value3 or the other way around (ORDER BY `values_column` IS NULL ASC): [values_column] value1 value2 value3 NULL NULL I checked JDO 3 specification and found that JDOQL's ordering specification doesn't support specifying NULL values handling: -- 26.7 Ordering Specification This section describes the syntax of the setOrdering argument. OrderingClause: OrderingSpecs ,opt OrderingSpecs: OrderingSpec OrderingSpecs , OrderingSpec OrderingSpec: Expression Ascending Expression Descending Ascending: one of asc ascending Descending: one of desc descending Please note, as a usability feature OrderingClause supports an optional trailing comma. -- Thank you for your time and efforts. -- This message is automatically generated by JIRA.

AI Craig update Chapter 11. I compared Appendix K with chapter 11.6 Optional Feature Support of the spec and found two missing entries in Appendix K: - javax.jdo.option.List - javax.jdo.query.JDOQL 2.
